Fabricated concrete beam-column connecting joint

LI CHENG

The invention provides a fabricated concrete beam-column connecting joint. The fabricated concrete beam-column connecting joint comprises a prefabricated column, a prefabricated beam and a joint connecting component for connecting the prefabricated column with the prefabricated beam, wherein hole channels are reserved in the prefabricated column, and beam longitudinal bars are pre-buried in the prefabricated beam. The joint connecting component comprises steel bars, reinforcing steel bars, stirrups and cast-in-place concrete; and the four layers of reserved hole channels are formed in the prefabricated column, the steel bars penetrate through the hole channels, are connected with the beam longitudinal bars through welding and are fixed through the stirrups, and the cast-in-place concrete is poured in a beam-column connecting joint area. According to the fabricated concrete beam-column connecting joint, through the joint connecting component composed of the steel bars, the steel bars and the cast-in-place concrete, connection between the prefabricated column and the prefabricated beam is achieved, the connecting component is simple in structure and good in integrity and has excellent anti-seismic property, the industrialization efficiency of the fabricated concrete beam-column connecting joint is remarkably improved, and universalization and standardization can be achieved.
